As expected, in ALL-SIL cell line in which the expression of STAT6 was knocked down (Figure 4A and Figure S6), we observed a significant cell proliferation decrease after 48 h of dexamethasone treatment at 1–0.01 μM compared to control measured both by MTT assay and EdU staining (Figure 4B,C). Here, STAT6 is linked to acute lymphoblastic leukemia.
